Question

What is x? Can you please help?

Answer 1

The answer to your question is: x = 2

Explanation:

Data

LM = 6x

MN = 10x + 4

LN = 20x - 4

x = ?

Process

LM + MN = LN

Then

6x + 10x + 4 = 20x - 4

Solve for x 16x + 4 = 20x -4

16x - 20x = -4 - 4

-4x = -8

x = -8/-4

x = 2

6(2) + 10(2) + 4 = 20(2) - 4

12 + 20 + 4 = 40 -4

36 = 36
